Lars Hjemli 4a0be58666 Add cgit_diff_link()
This adds a new function used to generate links to the diff page and uses
it everywhere such links appear (expect for single files in the diffstat
displayed on the commit page: this is now a link to the tree page).

The updated diff-page now expects zero, one or two revision specifiers, in
parameters head, id and id2. Id defaults to head unless otherwise specified,
while head (as usual) defaults to repo.defbranch. If id2 isn't specified, it
defaults to the first parent of id1.

The most important change is of course that now all repo pages (summary, log,
tree, commit and diff) has support for passing on the current branch and
revision, i.e. the road is now open for a 'static' menu with links to all
of these pages.

                       cgit - cgi for git


This is an attempt to create a fast web interface for the git scm, using a
builtin cache to decrease server io-pressure.


Installation

  $ make
  $ su
  $ make install

This will install cgit.cgi and cgit.css into "/var/www/htdocs/cgit".

Note: The initial "make" will create a submodule 'git' and clone the git
repository at git://git.kernel.org/pub/scm/git/git.git in it. If you
already have a local git git repository that you want to use as origin
for the submodule, run

  $ git clone -s <path-to-git-repo> git
  $ ./submodules.sh -u

before running "make".


Dependencies

  -git (1.5.2-rc0 or newer, due to git submodule) installed
  -zip lib
  -crypto lib
  -openssl lib


Apache configuration

A new Directory-section must probably be added for cgit, possibly something
like this:

  <Directory "/var/www/htdocs/cgit/">
      AllowOverride None
      Options ExecCGI
      Order allow,deny
      Allow from all
  </Directory>


Runtime configuration

The file /etc/cgitrc is read by cgit before handling a request. In addition
to runtime parameters, this file also contains a list of the repositories
displayed by cgit.

A template cgitrc is shipped with the sources, and all parameters and default
values are documented in this file.


The cache

When cgit is invoked it looks for a cachefile matching the request and
returns it to the client. If no such cachefile exist (or if it has expired),
the content for the request is written into the proper cachefile before the
file is returned.

If the cachefile has expired but cgit is unable to obtain a lock for it, the
stale cachefile is returned to the client. This is done to favour page
throughput over page freshness.

The generated content contains the complete response to the client, including
the http-headers "Modified" and "Expires".


The mis(sing) features

Submodule links in the directory listing page have a fixed format per
repository. This should probably be extended to a generic map between
submodule path and url.


The end.
